That FPU handles PID loops, FFTs, and sensor-fusion math in hardware — no software emulation, no cycle penalty. For a motor-drive or industrial-gateway design, that means tighter control loops and more headroom for protocol stacks. ## 64 KB Flash, 24K x 8 RAM — sizing the firmware budget 64 KB Flash and 24K x 8 SRAM place this part in the mid-density tier of the Tiva C family. It fits applications like a CAN-to-UART bridge, a brushless-DC motor controller, or a sensor hub aggregating SPI and I²C peripherals. If your firmware needs a full RTOS plus a TCP/IP stack, you will be counting bytes — this is not the 2 MB part for a GUI-heavy design. ## Connectivity set — CAN, USB OTG, and serial options On the peripheral side, this MCU carries CAN, USB OTG, and multiple UART, SPI, I²C, and SSI interfaces. That combination suits it for designs that talk to a PLC over CANopen while logging data to a USB stick and polling an external ADC over SPI. ## Industrial temperature range — where it goes","metaTitle":"TM4C1237D5PMIR Tiva C MCU, ARM Cortex-M4F 80 MHz","metaDescription":"Texas Instruments TM4C1237D5PMIR ARM Cortex-M4F MCU, 80 MHz, 64 KB Flash, 24K x 8 RAM, -40°C to 85°C, 64-LQFP.
